Hydrophone fix?

[Adooo]

Hi. I have some questions about the hydrophone...

I know it was bugged before TDW fixed it but i would like to know how is it working now...How is the range calculated?

Example : Lets say there is a convoy with 10 ships. I have noticed that the range is always reported for just 1 of those 10 ships, no matter what bearing i choose at the hydrophone...If i put it at bearing 10 range is 2100 if i put it at bearing 30 and click on range again it is still the same 2100....so i guess it can only report for just 1 ship from those 10, nearest one? u sure? ...

I had a situation today... the closest ship was at 1870 range when i checked with stadimeter (twice and went to hydrophone and asked for report nearest contact , estimate/precise range, the bearing was correct but the range was like 2400 with TDC off and like 3200 estimate/ 6000 precise with TDC on so nothing correct WTF? Did all checks within 10 secs so the ship could not move away too much so i guess the range was for a different ship from the convoy and not the closest one?

Also another question...Why are the range calculations different if u have TDC off or on?

If i remember right in SH4 u could get a precise range for every ship in the convoy, depending on what bearing u choose at the hydrophone...

Is it possible to fix the hydrophone so that it is showing the range depending on what bearing(ship) u choose? Would be a great thing!

Note : I have no problems if there is only 1 ship but it is impossible to hunt a convoy using only hydro.....

Using sh5.exe patched to v0.0.3, MO(patched), TDW 6.5.0, IRAI, Real navigation etc...
